IMPROVEMENT IN wAsH-BoiLERs.

Specification forming part of Letters Patent No. 130,830, dated August 27, 1872.

Specication describing ce1-tain Improvements in Wash-Boilers, invented by JOSEPH C. TILTON, of the city of Pittsburg, in the county of Allegheny and State of Pennsylvania.

My invention relates to that class of washboilers which are made with a false bottom,

and have pipes or passages leading to the top oftheboiler,through whichthehotwaterpasses from below the false bottom while the cold `water enters the water-space thus left vacant -V through the valves in the false bottom; and

consists in making the false bottom narrower Y than the boiler, and with sides which t into l. deep grooves secured to the bottom of the boiler and reaching its entire length, and in themanner of securing the false bottom in poy sition 3 the object of this arrangement being to make the false bottom water-tight, or nearly so, and force all the heated water to pass out through the pipes provided for that purpose.

Inthe drawing, Figure l is a perspective view ot' my boiler, the side being brolren away to show the false bottom; Fig. 2, a cross-section of the bottom of the boiler; Fig. 3, a crosssection of the boiler; and Fig. 4, a vertical central section ot the same.

A is the boiler; B, false bottom 5 F F, hotwater passages leading from below the false bottom through which the hot water passes to the top of the boiler in the direction of the arrows; b b b, holes in false bottom, through which the cold water passes into the water- 'space below the false bottom; E, movable 'plate which closesthe holes b b b when the Y iva-ter below the false bottom becomes heated;

as shown at d d, Fig. 4. The false bottom is l inserted by sliding one end under one of the pipes F far enough to allow the false bottom to drop into its place in the grooves O O. It is then moved slightly along so as to hook both ends under the edges of the pipes F F, asfshown in Fig. 4. The V-shaped sides ot thej'alse bottom fitting snugly -in the correspondingly-shaped grooves O O, attached to the bottom of the boiler, prevent the heated water and steam from escaping at the sides ot' the boiler, and lifting or iioating the clothes, and force it-t'. e., the heated water-to rise in and escape through the holes in the passages F F and flow onto the top of the clothes.

\Vhat I claim as my invention, and desire to secure by Letters Patent of the United States, is

The false bottom B having the V-shaped sides D D, in combination with the boiler A having the grooves C O and hot-water passages F F, when arranged and operating as and for the purposes specified.
